建立以蜆開闔律動行為模式作為監測水域水質關鍵指標之應用介面

Modeling clam behavioral rhythm as a key index for an interface implement of monitoring water quality

本計畫以過去所開發之線上雙殼貝開闔行為監測系統裝置，觀測蜆群暴露在不同水體環境（自來水、埤湖水、河水、地下水及灌溉水）中，每天開闔律動行為變化。我們將其所觀測之蜆殼開闔及暴露水質之資料，以統計方式建立其水中開闔行為模式與水質之相關性建立對應資料庫。在應用端結合此水域環境中雙殼貝開闔行為監測系統裝置，所發展的判別水域水質關鍵指標的應用介面模式，可作為未來水域環境之生物預警監測系統資料庫。

By employing our past developed clam rhythm-based online behavioral monitoring system, valve daily rhythmic responses of bivalves exposed to various aquatic environments (piping, lake, river, groundwater and irrigation canal) were observed to construct the database for a comparison of various water quality parameters. With the integration of a statistics-based approach and a four-parameter lognormal model, bivalve behavioral rhythms of C. fluminea exposed to various unpolluted environments were described to obtain the according relationship between valve rhythmic features and various water quality conditions. Our outcomes reveal that a clam rhythm-based online behavioral monitoring system can be used to further develop an interface implement for monitoring and identifying the level of water quality status. In the future, the developed interface model describing the according relationship between water quality parameters (pH, turbidity, hardness and electrical conductivity) and valve rhythmic features can be used as a database of a clam-based early warning system for monitoring and identifying the level of water quality status.
